Super size Bumble bee

Can you therefore tell me how I this explain to a bumble bee. He/she has just flown into my kitchen, and it is ginormous. Must be at least one inch in diameter, very dark in colour, and makes a noise like a grass strimmer, only possibly louder. He has now gone into the dining room, and I have shut the door on him. What do I do now? Can I have a volunteer please to let him out, by opening the patio doors?

Funny, innit!
Bees show their mates a little dance of where to find the creme de la creme (in pollen terms, of course) that can be up to several miles away, yet they fly through an open window into a room and CAN'T GET OUT AGAIN!
I don't get it!

I'm OK with Bees, but absolutely detest Wasps with a passion. You just sit outside with a drink of some grub and they're on you in seconds buzzing here there and everywhere around us. The kids make a fuss and then you wonder why you bother. This spring there seems to be an awful lot of big fat wasps outside the house looking for nesting sites. I fear it's gonna be a very waspy year. I'm swatting thenm as fast as.

Recent tip to help catch em is grab an aerosol spray, deodorant, hairspray, whatever, it temporarily coats 'em and they usually hit the deck for long enough to have 'em.
